La sonda emette un fascio di onde ultrasoniche obliquamente verso l\u2019alto. Le onde ultrasoniche si propagano nel fluido. Il fluido pu\u00f2 contenere impurit\u00e0 quali bolle o particelle (si pu\u00f2 considerare che le impurit\u00e0 presenti nel fluido abbiano la stessa velocit\u00e0 del flusso d\u2019acqua). Quando le onde ultrasoniche entrano in contatto con le impurit\u00e0 presenti nel fluido, le onde ultrasoniche riflesse producono uno spostamento di frequenza Doppler \u0394f. Lo spostamento di frequenza Doppler \u0394f \u00e8 proporzionale alla velocit\u00e0 di flusso. La velocit\u00e0 di flusso del fluido pu\u00f2 essere misurata rilevando lo spostamento di frequenza Doppler \u0394f.<\/p>\n<h3><strong>2.
